Definitions

  • the invention relates to a vacuum cleaner according to the preamble of claim 1.
  • exhaust ducts are well sealed to the exhaust filter so that no dust-laden air escapes from the vacuum cleaner. After the exhaust filter so far less attention was paid to a dense airway, as the air is filtered and therefore clean.
  • the exhaust air is passed through an air duct, which is formed by at least one housing part, from the vacuum cleaner into the environment. Usually, the exhaust air is blown out of a duct in the upper housing part upwards.
  • vacuum cleaners in which the exhaust air over a lateral region of the vacuum cleaner, for. is derived under the bumper.
  • An object of the invention is accordingly to provide a vacuum cleaner in which the above-mentioned disadvantages are avoided.
  • a fan room and an exhaust filter for exhaust air generated in the blower chamber wherein the exhaust filter is arranged in a blower downstream flow exhaust filter housing, and at least one housing part, which downstream of the exhaust air downstream of the exhaust filter Air path forms, provided that at least one seal is disposed in the further air path behind the exhaust filter.
  • the advantage of the invention is that it is prevented by the seal that hot exhaust air escapes into unwanted areas of the vacuum cleaner.
  • damage caused by the hot exhaust air can be prevented at the components which are arranged in adjacent housing sections or areas.
  • this can reduce the temperature in the entire vacuum cleaner, which makes sense if the vacuum cleaner is operated for a longer period of time.
  • the plastic used in the vacuum cleaner or in the region of the exhaust ducts must be less stable to thermal deformation and can therefore be less expensive. Noises that occur when exhaust air escapes through leaks are prevented, are prevented, so that the acoustics of the vacuum cleaner improves during operation.
  • the seal is arranged on at least one transition from the exhaust air filter housing to the housing part.
  • Characterized structurally related joining zones between the exhaust air filter housing and the housing part are sealed. Joining zones or air gaps may e.g. arise because the housing part is designed to be hinged or removable.
  • the air path is preferably formed by the exhaust air filter housing and the housing part and the exhaust air filtered with the exhaust air filter escapes via openings of the housing part.
  • the seal preferably closes off the airway in the direction of a further housing part, which comprises the vacuum cleaner electronics.
  • the seal is formed of an elastic material. This allows a movement of the housing parts on which the seal is arranged, such. opening or closing the housing part, which allows access to change the exhaust filter.
  • the seal may be disposed on the exhaust air filter housing or the housing part. It can e.g. glued and / or placed around an edge of the housing part.
  • Fig. 1 schematically shows a simplified plan view of a vacuum cleaner 10.
  • exhaust air 12 Fig. 2
  • Fig. 2 exhaust air 12
  • Fig. 2 schematically simplified shows the vacuum cleaner 10 in a sectional side view along the section line AA in Fig. 1 ,
  • a dust chamber 16 in which dust from the sucked up with the vacuum cleaner 10 air, for example, in a dust bag, is deposited
  • a blower chamber 18 is shown with a blower unit 19.
  • the exhaust air 12 is filtered with an exhaust filter 20, which is arranged in an exhaust air filter housing 22, and then passed out of the vacuum cleaner 10.
  • the exhaust filter 20 may be, for example, a coal, HEPA or textile filter.
  • the exhaust air 12 is blown through a provided with openings 24 housing upper part 14 of the vacuum cleaner 10 from the vacuum cleaner 10.
  • the housing upper part 14 is pivotally mounted in a known manner and serves to close the dust chamber 16 and to cover the exhaust filter 20. It has a peripheral wall 26, which is folded in the direction of the exhaust filter housing and forms an air path 28 with this.
  • Fig. 3 is an enlarged view of the in Fig. 2 Part B of the vacuum cleaner 10, as known in the art.
  • the exhaust filter 20 and the housing top 14 provided with openings 24 at the top 14 of the vacuum cleaner 10 is shown with the wall 26.
  • An air path 36 of the exhaust air 12 is airtight to the exhaust filter 20, so that no dust can escape from the vacuum cleaner 10. This is achieved, for example, by a seal 31 in the region of adjacent housing components.
  • Arrows make it clear that after passing through the exhaust filter 22 clean, but generally heated exhaust air 12 can escape at a transition 32 from the exhaust air filter housing 22 to the housing part 26 via an air gap from the exhaust duct 28 into the adjacent housing portion 38. This is avoided with the invention. Air gaps in the exhaust duct 28 are usually by design, since z.
  • the upper housing part 14 is pivotally or removably designed to allow replacement of the exhaust filter 20 or a rod bag (not shown). Therefore, it can not play-free and therefore not airtight with the exhaust filter housing 22 complete.
  • the adjoining housing area 38 lies, for example, in the direction of the vacuum cleaner electronics, not shown, so that the generally warm exhaust air 12, which reaches this area or even the vacuum cleaner electronics, can cause damage to the local components by overheating.
  • Fig. 5 now shows the already in Fig. 4 shown area, only this time as it is provided in a vacuum cleaner according to an embodiment of the invention, namely with a seal 34.
  • the seal 34 is disposed at the transition 32 from the exhaust air filter housing 22 to the wall 26 and prevents that at this transition 32 the Exhaust air 12 can escape from the airway 28 in the adjacent housing portion 38.
  • the seal 34 may be made of a resilient material that allows the housing top 14 to be movable with the wall 26 and to be correspondingly opened and closed.
  • the seal 34 may be disposed either on the exhaust air filter housing 22 or on the upper housing part 26.
  • the airway 28 (FIG. Fig. 2 ) the exhaust air 12 ( Fig. 2 ) also in a side region of the vacuum cleaner 10 (FIG. Fig. 1 ), in which runs, for example, a bumper.
  • the bumper prevents damage to objects that the vacuum cleaner 10 may encounter when it is moved in use. Is provided that the Exhaust air 12 is passed into this area, the bumper is provided with corresponding outlet openings for the exhaust air.
  • the upper housing part 14 ( Fig. 2 ) with the openings 24 ( Fig. 2 ) is located at a rear side of the vacuum cleaner 10, at which generally an outlet for a power cable of the vacuum cleaner 10 is arranged.
  • the exhaust duct 28 is designed such that the exhaust air 12 through the exhaust filter 20 (FIG. Fig. 2 ) reaches the rear of the vacuum cleaner 10 and is conducted there to the outside.
  • the invention can be briefly illustrated as follows: It is a vacuum cleaner 10 with a dust chamber 16, a blower chamber 18 and an exhaust filter 20 for exhaust air 12 generated in the blower chamber 18 indicated in which in a further air path 28 behind the exhaust filter 20 at least one seal 34 is arranged so that prevents exhaust air 12 passes into one or more adjacent housing portions 38.
  • the exhaust air filter 20 is arranged in an exhaust air filter housing 22 and on one side of the vacuum cleaner 10, a housing upper part 14 provided with openings 24 is arranged in a region of the exhaust air filter 20, through which the exhaust air 12 can escape.
